Windshield HUD Using Luminescent Particles for Lane Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up displays (HUDs) for vehicles often require coatings on windshields that reduce transparency, limiting their application to specific regions and hindering the presentation of critical information to drivers, especially in dynamic environments.
Innovation Solution
A substantially transparent windscreen HUD system utilizing light-emitting particles or microstructures that allow for luminescent displays while maintaining visibility, enabling the projection of graphical images representing the vehicle's operational environment, including lane guidance and navigation information, by monitoring various sensors and data inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light is projected directly upon the windscreen to create a head-up display, then information can be presented to the operator, but the transparency of the windscreen is significantly decreased
Solution Approach 1:
The windscreen is divided into a first region and a second region. The first region remains substantially transparent for viewing, while the second region contains the head-up display information. This segmentation allows both transparency and information presentation to coexist without compromising either function.
2Ease of manufacture
If coatings or materials are applied to the windscreen to enable head-up display, then light can be projected for display, but the display is restricted to limited regions upon the windscreen
Solution Approach 1:
Different regions of the windscreen are assigned different optical properties. The first region maintains substantial transparency while the second region is configured to display head-up information. This local differentiation allows the display to be implemented without compromising overall windscreen transparency and enables flexible positioning of display content.

Function Achieved in This Case
Enables the display of critical operational information on the windshield without obstructing the driver's view, enhancing safety and operational awareness by providing a clear and transparent interface for lane guidance, navigation, and environmental data.
Implementation Method 1
one of light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen
Data Source
AI summary
A substantially transparent windscreen head up display includes one of light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen. A method to represent graphical images upon a transparent windscreen head up display of a vehicle describing transit of the vehicle with respect to a lane of travel includes monitoring informational inputs describing an operational environment of the vehicle. Monitoring these informational inputs includes monitoring a desired lane of travel, and monitoring a current position of the vehicle. The method further includes determining a relationship of the desired lane of travel to the current position of the vehicle, determining a graphic describing the relationship of the desired lane of travel to the current position of the vehicle, and displaying the graphic describing the relationship of the desired lane of travel to the current position of the vehicle upon the substantially transparent windscreen head up display.
